PURPOSE: A full automatic sealed door with a soundproofing function of a shield door is provided to block and absorb a sound by completely shielding an inner side and an outer side with an equal-shielding point. CONSTITUTION: A full automatic sealed door is comprised of a door frame(100), a door body(200), a door transfer device, and a control unit(400). The door frame has a shielding door frame(120) without a protrusion from a surface. The door body slides to be opened and closed. The door transfer device includes a ball screw(322) rotated by a driving motor(326), a plurality of fixing plates(323) for left and right transfer, and a linear bearing(324) combined with the fixing bearing. A soundproofing plate(250) with a honeycomb structure is formed in the door body to block the sound. The control unit controls the open and close operation of the door transfer device.
